WATER-HEATIN Gr DRUM.

Application filed June 13, 1919.

T 0 all whom it may concern Be it known that I, ALFRED T. FowLEs, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Water-Heating Drums, of which the following is a specification.

This invention relates to water heating. drums of the type especially designed for use in connection with water heaters of the type described and claimed in my copending application for patent for water heater, Serial Number 304,- 041, filed June 13, 1919, Patent No. 1,382,- 495, dated June 21, 1921, and the in vention has for its primary object to provide an improved drum of such shape and construction as to afford maximum heating efliciency at a minimum expenditure of fuel.

With this and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction combination of elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claim appended hereto.

Figure 1 represents a side elevation of the improved water drum.

Figure 2 represents a diametrical vertical sectional view therethrough in the plan of the outlet port.

Figures 3 and 4 represents top and bottom plan views, respectively, of the drum.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the body of the drum which is in the form of a hollow annulus or ring having an inclined top wall 6 whereby the internal water containing chamber 7 increases in depth from one side of the ring to the other to assist the flow of water therefrom, the side wall of the relatively deep water portion of the chamber having the hot water outlet port 8 therein adapted for connection with a hot water'pipe whereby the water is exhausted from the drum when heated. The lower portion of the annular member 5 communi- Serial No. 304,042.

axis of the annular member 5. The spaces 10 between the respective extension 9. communicate with the central opening 11 through the annular body member 6 thereby providing a continuous passage through the drum for the products of combustion arising from the burner which is adapted to be arranged thereunder.

The upper and lower portions of the point of juncture between the extensions 9 are provided'with internally threaded extensions 12 and 13 adapted for connection with a cold water supply pipe and drain pipe respectively. By this construction, it will be readily apparent that since the cold water is conducted to the radial extensions 9 through the port 12 and withdrawn through the outlet 8 in the side of the body, the hot water does not become chilled as is common with those devices wherein the hot water pipe passes through the cold water in the boiler, becoming chilled by the time it reaches the top of said boiler. Moreover the device is such as to dispense with special pipe fittings and thus is capable ofuse in connections with the ordinary common type of hot water boilers now in common use. In addition, it will be also recognized that the device is such as to permit of cleaning, all portions being easily accessible for that purpose which constitutes an advantage over other devices designated for similar use.

In use, the water to be heated is introduced into the drum through the port 12 and entering the hollow extensions 9 is heated therein by contact. with the heated wallsof the extensions and arising enters the circular chamber 7 from which the water is finally conducted through the port 8. The flame from the burner (not shown) is directed upon lower surfaces of the extensions 9 and upon the lower surface of the bodyv member 5 and entering between the extensions and entering the central aperture 11 of the body member 5 effectively retains the v I I 1,429,863
